Thanks to both Alan and "light and variable". I understand the mast step potential problem, but I am sailing in light summer winds on Long Island. Hopefully everything will stay upright! I just have to find a donor rig to experiment with. Thanks again for the advice.
Has anyone figured out how to rig the 2.5" diameter mast of a Laser/Force 5 into the 2.25" mast step of a Sunfish. I am trying to recreate the old Super Sunfish rig once sold by AMF which had the same 2.25" diameter mast as the standard Sunfish rig.
